I think that the best way to profit from short-term investments in the crypto market is trading on the stock exchange with a profit from 1% to 5%. But you must understand that this is a big risk. You also need to have knowledge of technical analysis and analyze the news of the crypto market.
If you know how to trade successfully that is the only thing I can see for you to earn profit in a short period of time. You can also do investing but it will take time for you to gain your profit.
